Sentinel Peak

Sentinel Peak, Mountain summit in Tucson, United States.

Description

Sentinel Peak is a volcanic mountain summit in the Tucson Mountains west of the Santa Cruz River, rising approximately 884 meters above sea level. The peak consists of multiple layers of volcanic rock that once extended throughout the current Tucson Basin area.

History

Spanish forces established a sentinel post on the peak in 1775 near the Presidio San Agustín del Tucson to watch for Apache warriors. The strategic location served as a defense point for the early Spanish settlement in the region.

Culture

The large white letter A on the mountainside was painted by University of Arizona students and faculty in 1914 and remains an iconic symbol of the city. The letter is visible from across Tucson and continues to be maintained by the university community.

Practical

Designated hiking trails lead to the summit and several observation points offering views across Tucson and surrounding mountain ranges. The mountain is accessible year-round, with early morning hours providing the best conditions and fewer crowds.

Did you know?

The name derives from the Spanish watchpost that was established here centuries ago and remains deeply woven into the site's identity. Visitors can trace the sight lines that once served the region's defense strategy.
